Function RM_GetClientCertificate

app/redis-6.2.6/src/module.c:6628–6639

Return the X.509 client-side certificate used by the client to authenticate * this connection. * * The return value is an allocated RedisModuleString that is a X.509 certificate * encoded in PEM (Base64) format. It should be freed (or auto-freed) by the caller. * * A NULL value is returned in the following conditions: * * - Connection ID does not exist * - Connection is not a TLS connecti

 * - Connection is a TLS connection but no client ceritifcate was used
